Original applim'rtitui filed February 12, 1910, Serial 1T0. 548,582, and

in Canada January. 26, 1918.' Divided and this application filed October 27, 1925, Serial No. 65,189.

The invention herein claimed relates to the art of feeding glass for the manufacture of pressed or blown articles, such as tableware and the like. I

The structure herein shown comprises a chamber for holding molten glass, having 'a discharge orifice in the bottom, in which chamber vertically reciprocates in alignment with the orifice a'plunger to control the issue of glass from the orifice. In another application, Serial No. 759,172, also filed as a division of the original application of THEODORE C. STEIMER (deceased), mechanism for reciprocating the plunger and for determining the limits of its path of movement are described in detail and claimed. The present application has for its object to claim the means by which such plunger is mounted and guided for movement.

Referring to the accompanying drawings which are part. of those filed in the original application aforesaid, and which show, in addition to the features herein claimed, certain matters to be claimed in the aforesaid original application, and other divisions thereof,

Figure 1 is a partial side elevation and artial section of the mechanism invented y THEODORE G. STEIMER,'and embodying the subject-matter of this application, the sec tion being taken partially on the line 13 of Figure 2. Figure 2 is a section thereof and an elevation of a different view of the same mechanism.

Figure 3is a plan view of parts shown in the aforesaid figures.

To explain briefly the general nature of this invention, it may be stated that the chamber 45 has therein a pot 46 containing glass, which by means of a reciprocating plunger 58 is divided as it issues from the bottom outlet 59. The plunger, which does not contact with the walls of the submerged outlet 59, serves to control the issue of glass from the outlet and its delivery to the mold M. The chamber 45 has the double purpose of housing the regulating pot and plunger, andof keeping the glass uniform at the correct temperature. Inside the chamber 45 and beneath the pot 46 a by a burner 47.

Located adjacent to the chamber are vertical guides 55, in which slides a frame 54 which carries a plunger 58 controlling the issue of glass from the outlet. The frame is given a vertically reciprocating motion by mechanism specifically claimed and described in the aforesaid divisional application, Serial gas flameis introduced or rrrrrsnunen, PENNS LVANIA, BY ZANESVILLE, onro, ASSIGNOR, BY MESNE- comramr, or namrronn, connnc'rrcur, .A

No. 759,172, and has on its upper end an outwardly projecting horizontal bracket 54 channeled on its upper face, the inner end of the bracket being formed into a saddle 54*, while a well 54 is formed in the outer end of such bracket. A plunger .supporting arm 56 has its depending outer end 56 located in the well 54 of the bracket of the frame, the body of the arm being in the channel of the extension and projecting therefrom'inwardly to above the orifice 59 in the pot, where it is formed into a ring to receive the conical upwardly flaring head of the plunger 58, which is normally held onits seat in'the ring by meansof the leaf spring 62.

The arm 56 may be ad usted and locked lengthwise of the channel by the screws 54 in the bracket and laterally by the screws 54 and 54, which engage inclined faces 56 on the rear end of the arm and hold the same depressed. The weight of the plunger is carried by the saddle 54. A vertical screw 54 in the bottom of the well serves to lift the rear end of the arm and in to considerable warping. By this invention,

the lower end of the plunger when the latter is in its lower position, I may be accurately positioned axially of the aperture, and without contact with the latter, which is of imglass having an outlet, a vertical guide adportancejas a lateral displacement of such ower end of the plunger at such time may resultfindestroyingthe symmetry of the issued glass.

What Iclaim as the invention of THEO- DORE-G. STEIMER is:

. 1. In an apparatus for delivering glass,

the combination with a heated chamber containing molten glass and having an orifice for the flow of glass therefrom, of a frame having a ring axially above the orifice, means for reciprocating such frame, a part controlling the flow of the glass through the orifice having a head upon its upper end supported in such ring, and resilient means for depressing the-part in respect to the frame.

2. In an apparatus for delivering glass, the combination with a container fortlie lass having an outlet, a vertical guide adacent to the container, a frame sliding on the said guide, means for reciprocating the -frame, an arm projecting from the frame to a position over the outlet, means for adjusting said arm tiltably and slidably on the frame to move the projecting end of the arm 7 relatively to the outlet, and a plunger carried by the projecting end of the frame. and cooperating with the outlet.

3. In'an apparatus fordelivering glass, the combination with a container forthe jacent to and outside of the container. a. slide working on said guide, means for vertically reciprocating the slide, and a'plunger cooperating with the outlet to control the discharge of glass therethrough, said plunger being movable by the slide and held rigidly against lateral movement with respect to the slide and yieldingly against right line movement in one direction in respect to said slide.

4. In glass feeding apparatus. a glass container having a submerged discharge outlet,

an implement," and means detachablv connected with said implement to hold the im plement for movement in adhesive contact with the glass relatively to theoutlet. said implement holding means including a resil ient member tending to prevent relative movement of the implement and its holder.

5. In glass feedingapparatus, a glass container having a submerged outlet, .1 discharge control implement extending into the glass'toward the outlet and adapted when operated to move relatively to the outlet, an-

arm having means embracing a portion of the implement and cooperating with the implement to prevent axial-movement of the implement in one direction relatively to said arm, a resilient means carried by said arm for yieldingly preventing axial movement of the implement relatively to the arm in the opposite-direction, and means for supporting said arm for movement to operate said implement.

6. In glass feeding apparatus, a glass con tainer having a submerged outlet in its base, a vertically reciprocable operating means adjacent to the container, an arm fulcrumed intermediate its length on said operating means for limited swinging movement about a horizontal axis and so that an end portion of said arm extends above said outlet, .an implement carried by said end portion of the arm in position to depend into the glass in the containertoward' said outlet, and means connecting the other end of said arm with said vertically reciprocable operating means, said connecting means being adjustableto swing said arm vertically on its fulcrum and to thereby change the position of the lower end of the implement relatively to the outlet.
